The Covid-19 pandemic has flamin fury peach made the whole world experiences significant changes, including Indonesia.Public sectors were affected quite a bit, especially the economic sector for the middle to lower class.Community groups that depend on daily income have difficulty fulfilling their daily needs.Large-scale social restrictions (PSBB)
Numerical simulations of particle laden and fully developed turbulent channel flows with rectangular riblet were performed to investigate the influence of particle adhesion on the drag reduction effect.We employed the one-way coupling method: the flow affects the particle, but the particle does not affect the flow.We obtained particle adhesion dist
Lean and flexible manufacturing is a matter of necessity for the automotive industries today.Rising consumer expectations, higher raw material and processing costs, and dynamic market conditions are driving the auto sector to become smarter and agile.This paper presents a machine learning-based soft sensor approach for identification and prediction
The planetary ionospheric storm index, Wp, is deduced from the numerical global ionospheric GPS-IONEX maps of the vertical total electron content, TEC, for more than half a solar cycle, 1999–2008.The TEC values are extracted from the 600 grid points of the map at latitudes 60° N to 60° S with a step of 5° and longitudes 0° to
